Eggs are tasty and nutritious, but have you ever hesitated to cook them because of that strange fishy odor?
This smell tends to stand out even more in soft dishes like steamed eggs, soups, and omelets, making it a bit disappointing.

Even when using fresh eggs, why does this smell occur?
Don’t worry.
This article covers everything from the cause to the solution in one go.


What Causes the Fishy Smell in Eggs?

1. Decreased Freshness

  • Over time, a gas pocket (air cell) forms inside the egg.
  • The older the egg, the more severe the protein denaturation, increasing the chance of unpleasant odors.
  • Absorbing odors from the fridge is another major cause.

2. Incomplete Mixing of Egg White and Yolk

  • Egg whites are mostly water and protein, while yolks are high in fat.
  • If not properly mixed, the egg can cook unevenly, causing odor during cooking.

3. Cooking Temperature and Time

  • High heat can cause the area around the yolk to turn green and increase the smell.
  • Cooking gently at the proper temperature (around 80–85°C / 176–185°F) makes the texture smoother and reduces the odor.

5 Tips to Eliminate Egg Odor

1. Choose Fresh Eggs & Proper Storage

Method Description
Water Test An egg that lies flat in water is fresh
Storage Tip Store with the pointed end down, in a dedicated egg container

Fresh eggs are the most important foundation!


2. Remove Chalaza & Mix Well

  • Remove the chalaza: Taking out the white stringy part significantly reduces odor.
  • Strain through a sieve: Helps yolk and white mix evenly, improving texture too.

3. Use Cooking Wine, Sake, or Vinegar

Ingredient How to Use
Cooking wine/Sake Add 1 teaspoon per 2–3 eggs
Vinegar Add 1–2 drops to boiling water

Alcohol and acid help eliminate odor molecules and make shells easier to peel!


4. Add Salt Before Cooking

  • Adding salt 10–20 minutes before cooking and mixing with the egg helps break down proteins and reduce odor.

5. Finish with Spices!

Spice Effect
Lemon juice Neutralizes odor with a fresh scent
Ginger juice Great for steamed dishes and soups
Pepper Its pungent aroma masks the fishy smell

Summary: Odor-Free Egg Dishes Are Easy!

Choose fresh eggs → Remove chalaza → Mix well → Use cooking wine/vinegar → Finish with spices

Just remember these steps,
and you’ll be able to make steamed eggs, omelets, or boiled eggs without any fishy smell.

Try making a soft and fragrant egg dish for dinner tonight!
